摘要:
损伤评估方法是结构抗震性能研究的重要课题，也是确定结构抗震性能目标的基础。文章在系统梳理现有抗震评估方法的基础上，根据铁路圆端空心墩拟静力试验的实测滞回曲线，通过计算不同荷载等级下的损伤累积耗能和位移延性比，采用Park-Ang类损伤模型定量分析圆端空心墩的震损情况，结合实际桥墩加载过程中的损伤情况，对比研究了各损伤模型的优劣。基于曾华武模型建立了地震损伤水平与实测位移比的关系，实现了圆端空心墩抗震性能目标的量化。
Abstract:
The damage assessment method is an important subject in the study of seismic performance of structures, and it is also the basis for determining the objective of seismic performance of structures. On the basis of systematically collating the existing seismic damage assessment methods, according the measured hysteretic curves of pseudo-static test of round-end hollow piers, the ration of accumulated damage energy dissipation to displacement ductility are calculated under different load levels. Then Park-Ang damage assessment model is used to quantitatively analyze the damage status of the round-end hollow piers and in combination with the actual damage situation of pier during loading, the comparative study on the advantages and disadvantages of various damage models is conducted. Based on Zeng Huawu's model, the ratio relationship of seismic damage level to measured displacement is established, which helps to quantify the seismic performance objective of round-end hollow piers.
